Cold forming

We offer cold forming as a stand-alone service or combined with welding and/or heat treatment. The methods used in cold forming are dishing, flanging and spinning, roll bending and press bending.

Dishing

In this manufacturing method the blank is dished in a hydraulic press to meet the spherical radius of the end. The knuckle radius is flanged in a spinning machine. We have seven hydraulic presses that can dish steel plates up to a thickness of 80 mm. Dished discs of over 8000 mm in diameter are manufactured by welding individual plates together.

Flanging and spinning

Our most frequently used manufacturing method is flanging and spinning. The method is best applied to small, tailor-made series. We have six spinning machines with an R2 maximum of 950 mm. We can spin steel plates up to a thickness of 40 mm, while the maximum diameter of a spun end is 11 000 mm.

Roll bending and press bending

We have three plate rolls and one bending press that can form different steel products for industrial use. Plate rolls can roll steel plates up to 30 mm in thickness and 3500 mm in width. The bending press is 4200 mm in length and has a stroke of 300 mm and a nominal pressing force of 4000 kN.
